There was this movie my mother use to hire for me on VHS and I can't for the life of me remember the tittle. It was a children's animated cartoon with these weird little creatures that use to collect crystals all colours of the rainbow from in mines I think that's all I remember!! Anyone know the movie I'm talking about probably came out in the 80's

Might be the rainbowbright movie? Snow white had gem mining, what yime frame did it come out?
